@cloud-fan This approach mainly contain three steps. 1. Find the reused exchange. If exist, it will apply the DPP filter. 2. In order to reuse the exchange stored in `AdaptiveExecutionContext#stageCache`, we wrap the `AdaptiveSparkPlanExec `plan in `SubqueryAdaptiveBroadcastExec`. 3. `SubqueryAdaptiveBroadcastExec#executeCollect `will reuse the exchange in runtime by calling the `AdaptiveSparkPlanExec#getFinalPhysicalPlan()` ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
